IMPROVEMENT IN HINGES FOR GATES.

Specification forming part of Letters Patent No. l 13,788, dated April18, 1871.

To all whom t may concern:

Be it known that I, EDWIN D. NORTON, of Cuba, in the county ot' Alleganyand in the State of New York, have invented an Im provement inGate-Hinges5 and do hereby declare that the following description, takenin connection with the accompanying drawing hereinafter referred to,forms a full and exact specification of the same, wherein I have setforth the nature and principles of my said improvement, by which myinvention may be distinguished from others of a similar class, togetherwith such parts as I claim and desire to secure by Letters Patent.

My invention relates to that class of hinges which causes the gates ordoors to which they are attached to close themselves by the force oftheir own gravity; and the nature thereof consists in certainmodifications and improvements in the details ofthe construction of thesame, hereinafter described and shown.

In the accompanying drawing', which illustrates my invention and forms apart ot' the specification thereof, in which corresponding parts areillust-rated by similar letters, Figure l is a side elevation,illustrating the position of the parts composing the hinge when the gateis closed. Fie'. 2 illustrates the hinge when the gate is open.

The construction and operation of my invention are as follows:

In the drawing, letter A designates an angular post-plate. B representsthe double inelines upon which the eye of the hinge C rests. Edesignates a projecting pin cast solidly with or rigidly attached to thepost-plate.

The gate-plate F and doubleinclinedflange G are cast solid with the eyeC.

When the gate is turned the piece F rises upon the double inclines Buntil it assumes the position illustrated in FiO. 2.

The pin E, projecting from the post-plate, performs a double oflice. Itacts in combination with the doubleincline fiange Gr on the eye of thehinge to prevent the gate from being thrown from its hinges, and whenthe gate is thrown wide open it serves as a support for the gate-plate,and holds the gate in position.

Having thus described the construct-ion, operation, and relativearrangement of the component parts of my invention, I will indicate inthe following clauses what I claim and desire to secure by LettersPatent- 1. The eye of the hinge() when provided with the double-inclineguiding-Harige Gnpon the upper part, as and for the purpose described.

2. The combination of the post-plate A, projecting pin E, eye of thehinge C, doubleincline tlange G, and gate-plate F, when constructed andopera-ting together, as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand this23d day of January, 1871.
